George Will looks at the now infamous law:

The No Child Left Behind Act was passed overwhelmingly by the House (381-41) and Senate (87-10), but now liberals see that NCLB expresses essentials of Bush’s conservatism. Democratic presidential candidates have denounced it as a “federal intrusion” in state and local affairs — everyone knows how much liberals dislike such intrusions. Howard Dean, that perfect indicator of liberal passions, seemed to think that if tests reveal that many schools are failing their children, then drastic changes must be made to the … tests.

Yes, the tests can be improved, and schools should have somewhat more latitude regarding disabled students and those whose first language is not English. But many complaints about NCLB are not about marginal or easily adjustable matters.
